Solve the problem.

Geometry Triangles can be classified by their sides.

(a) An isosceles triangle has at least two sides of equal length. Determine whether the triangle with vertices (0, 0), (3, 4), and (7, 1) is isosceles.

(b) An equilateral triangle has all sides of equal length. Determine whether the triangle with vertices (−1, −1), (2, 3), and (−4, 3) is equilateral.

(c) Determine whether a triangle having vertices (−1, 0), (1, 0) and (0, ) is isosceles, equilateral, or neither.

(d) Determine whether a triangle having vertices (−3, 3), (−2, 5) and (−1, 3) is isosceles, equilateral, or neither.
